there was about 3 million added....it was @ 593 million and it showed 1-3-2020.
It stated on the 10-K that there was 596 million shares on 1-6-2020 but Share Structure updated today/yesterday.
I know its a small difference, but it did change from 1-3-2016 to 1-6-2020..... and from watching yesterdays trading, it looks like there will be more Shares the next time it updates.
